t-9
The mathematical expression for "nine less than a certain number" can be represented as ( x - 9 ), where ( x ) is the certain number. This expression indicates that you subtract 9 from that number.
The expression ( 5a - 9 ) can be represented by the phrase "five times a number ( a ) minus nine." This indicates that you first multiply the number ( a ) by 5 and then subtract 9 from the result.
n-9
To write the numerical expression for "nine less than thirteen squared," first, identify the components: "thirteen squared" translates to (13^2) or (169). Then, "nine less than" indicates subtraction, so you subtract 9 from this result. The final numerical expression is (13^2 - 9) or (169 - 9).
It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".
9(m-cubed)+(m-squared)
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.

3n-9
The expression "9a plus b" represents a mathematical expression where "9a" indicates nine times the variable "a," and "b" is another variable. To combine them, you simply add the two quantities together, resulting in the expression "9a + b." Without specific values for "a" and "b," this is as simplified as it gets.
